In my opinion, not many people will give up their seats. There is a healthy waiting list I would be surpised if it not sold out again.
I would also be suprised if they didn't have a larger bleecher section in the south end zone also, thus increasing capacity.
I also think they will sell some individual tickets again, but probably give those on the waiting list first dibs -- in fact in a perfect world, you would give everybody on the waiting list 2 games out of the 10, thus keeping everybody happy.
